A host of stars rocked up to the hot ticket of the season, the CR Fashion Book party, in Paris on Tuesday night and one really obvious trend emerged from the night: the plunging neckline.
Kim Kardashian led the plunge-pack, as usual, and donned a stylish bodysuit and suit pants ensemble by Riccardo Tisci for Givenchy. She added a huge statement brooch and red lips for extra glamour.
Selena Gomez was snapping at her heels for curve appeal in a satin halter neck jumpsuit, which she paired with jewels from de Grisogono.
Models Cara Delevingne and Joan Smalls arrived together and they also must have got the (imaginary) memo about dipped necklines with Joan working a lace and silk low-cut dress, and Cara taking things a little further with a barely-there bodysuit and see-through striped trousers.
According to the Daily Mail, the theme of the night was 'Inspired By Carine' in reference to CR Fashion Book's stylish Editor-In Chief, Carine Roitfeld. So there was a host of black designer outfits dotted around the room.
But Rose Huntington-Whiteley decided to eschew all-black and opted instead for a statement black, white and yellow striped halterneck jumpsuit, which did, of course, also work the chest-flashing trend.
And far be it for Miranda Kerr to miss out on the 'mammary movement'. The model looked super-pretty in a tiered sheer Spanish-inspired gown with a, yep, you guessed it, plunging neckline.
Other stars at the bash included Kim's mum and sisters, Kris and Kendall Jenner, as well as Nicky and Paris Hilton, who all also got in on the trend.
